1Area of stationary object
If multihop relay configurations are implemented to extend network coverage, then network coverage area is improved, but routing complexity and packet loss increase
Solution Approach 1:
The patent segments the routing process into distinct components: routing label assignment, identifier mapping, and radio bearer selection. Each relay node maintains a mapping table that segments the complex routing decision into manageable lookup operations, reducing packet loss at each hop while extending coverage area through multiple relay nodes.
Solution Approach 2:
The patent introduces routing labels as intermediary elements that mediate between source and destination identifiers. These labels act as intermediaries in the mapping process, enabling reliable packet delivery across extended multihop paths by providing a simplified reference that reduces routing complexity and improves delivery reliability.
2Productivity
If identifier mapping and routing management are implemented to improve packet routing efficiency, then routing efficiency is improved, but device complexity increases
Solution Approach 1:
The patent implements preliminary action by pre-configuring mapping tables at each relay node before packet transmission. The network node assigns routing labels and establishes identifier-to-radio-bearer mappings in advance, so that during actual packet routing, nodes simply perform lookup operations rather than complex real-time decisions, thereby improving routing efficiency while managing device complexity.
Solution Approach 2:
The patent changes the parameter representation by introducing routing labels as abstract identifiers that simplify the routing parameter space. Instead of managing complex destination addresses directly, the system transforms routing decisions into label-based lookups, improving packet routing efficiency while the structured mapping tables keep device complexity manageable.
3Measurement precision
If routing labels and mappings are assigned to manage traffic routing, then routing control precision is improved, but information overhead increases
Solution Approach 1:
The patent extracts the essential routing information into compact routing labels that are separate from the actual data payload. By taking out only the necessary routing identification elements and storing them in efficient mapping tables, the system achieves precise routing control while minimizing information overhead in the transmitted packets.

AI summary
Certain aspects of the present disclosure relate to methods and apparatus for wirelessly routing packets. One method includes storing a mapping of one or more identifiers to one or more radio bearers associated with one or more destination devices. Each identifier is mapped to at least one radio bearer associated with at least one destination device. The method includes establishing an association with a network node and receiving information indicative of the mapping from the network node. The method includes determining the mapping based on the information indicative of the mapping. The method includes obtaining a first packet containing a first identifier and mapping the first packet to at least a first radio bearer associated with a first destination device based on the mapping and the first identifier. The method includes transmitting the first packet wirelessly over the at least one first radio bearer to the first destination device.
